From f59625c83fa6a14bc71cc07f4d87314030315514 Mon Sep 17 00:00:00 2001 From: Christopher Date: Tue, 27 Jan 2026 18:33:56 -0800 Subject: [PATCH] Revamp chat UI and add V2 encrypted messaging support Major update to chat page with new conversation list, message thread view, and support for V2 end-to-end encrypted messaging using DIDs. Adds chat lock state, message sending, conversation deletion, and improved polling. Updates user API and types to include DID and chatPublicKey. Fixes race conditions in feed loading, adds message button to user profile, and improves crypto and identity hooks for better locked/unlocked state detection. --- src/app/api/users/[handle]/route.ts | 1 + src/app/chat/page.tsx | 700 ++++++++++++++++++++-------- src/app/page.tsx | 18 +- src/app/u/[handle]/page.tsx | 38 +- src/lib/crypto/e2ee.ts | 29 +- src/lib/hooks/useChatEncryption.ts | 41 +- src/lib/hooks/useUserIdentity.ts | 13 +- src/lib/types.ts | 2 + 8 files changed, 626 insertions(+), 216 deletions(-) diff --git a/src/app/api/users/[handle]/route.ts b/src/app/api/users/[handle]/route.ts index 3a44de6..5d65e0c 100644 --- a/src/app/api/users/[handle]/route.ts +++ b/src/app/api/users/[handle]/route.ts @@ -97,6 +97,7 @@ export async function GET(request: Request, context: RouteContext) { isBot: user.isBot, publicKey: user.publicKey, // RSA key for signing chatPublicKey: user.chatPublicKey, // ECDH key for E2E chat + did: user.did, // V2 Identity };
